Super() confusion

I'm having a hard time understanding the proper syntax needed to override parent class methods with super(). Can someone help me understand how the code attached does not accurately override the add_item method from the Inventory class?

This is a code challenge that I am not passing, and per documentation on python.org as well as some answered questions below the super() video in the course, this syntax should be correct, but I am clearly wrong :)

inventory.py
class Inventory:
    def __init__(self):
        self.slots = []

    def add_item(self, item):
        self.slots.append(item)

class SortedInventory(Inventory):    
    def add_item(self, item):
        super().add_item()

Hi ! you were very close to the answer !! All you need to do is to add "item" to your line (: like this:

class SortedInventory(Inventory):    
    def add_item(self, item):
        super().add_item(item) # added

have a good day (:
